A kind of rotary platform type digital spray printing equipment and method of work thereof
(1) technical field:
The present invention is applicable to a kind of printing equipment, and being specially adapted to the cylinder is the printing machinery of stock, promptly a kind of rotary platform type digital spray printing equipment and method of work thereof.
(2) background technology:
Along with the high speed development of China's economic, the packing of commodity is more and more important.A good product is mixed exquisite packing not only makes the people pleasing, also can bring better economic benefit for businessman.So be packaged into for an important sales aid, also become a kind of means of manufacturer's competition.
The cylindrically shaped packaging thing is a kind of as packing, also needs various patterns on its surface and product is illustrated or makes product attractive in appearance to attract client.The existing widely used method in market is generally reprocessing behind the sheet material printed patterns is cylindrically shaped packaging thing such as pop can product.Columniform plastic product or glass product just can't adopt the method, generally can use the label that will print to be attached on the cylindrically shaped packaging thing.The label that sticks comes off easily through scraping, rub, meet situations such as water, and the use that influences product again so neither attractive in appearance makes overall product feel not enough class.Adopt traditional printing in addition, use the professional forme pattern is printed on the stock, but this type of mode need be manufactured the forme of specialty.Pattern or descriptive information are printed directly on the packing material, and with firm the linking together of packing material, the process that can also omit traditional printing plate-making is the important problem that market in urgent need solves.
In the mode of printing of realizing this series products, generally can adopt chain drive, drive clamping motion base frame (being the clamping stock) with chain and on locating platform, do intermittent movement, base frame needs detent mechanism when wherein need clamp and have guide rail guiding and intermittence to rest with chain, complex structure, the part processing difficulty is big, and the gap of chain also makes the machine positioning accuracy not high.At this type of problem, the transporting pattern that we are badly in need of designing a kind of structure optimization overcomes it.
The present invention's a kind of rotary platform type digital spray printing equipment and method of work thereof just can overcome the above problems.Utilize digital printed technology directly with spray printings such as patterns on stock.
